Bug Description

Yesterday (2021-11-15) I attempted to dist-upgrade my laptop running focal to jammy (`update-manager -d`). The upgrade initially proceeded, but failed early after apt reported gnome-control-center would be broken. I'm attaching the full logs from /var/log/dist-upgrade/.

Note: I eventually managed to upgrade to jammy by doing all intermediate upgrades (focal -> hirsute -> impish -> jammy), and overall the process was quite smooth. I didn't have to sort out updates breaking installed packages in that scenario, so the issue only affects the focal -> jammy upgrade, somehow.

Just tested in a clean and fully up-to-date focal VM, and the exact same error happens when trying to upgrade to jammy, so it's easily reproducible.

Editing /etc/apt/sources.list and replacing focal with jammy "works" but would end up removing the following packages which includes ubuntu-desktop.

The following packages will be REMOVED:
  gir1.2-mutter-6 gir1.2-unity-5.0 gnome-control-center gnome-shell-extension-desktop-icons gvfs-backends gvfs-bin libgc1c2 libmutter-6-0
  libsemanage1 libsmbclient libtss2-esys0 python3-ldb samba-libs ubuntu-desktop ubuntu-desktop-minimal

Ah, the upgrade isn't possible because the version of libsmbclient in Focal(-security and -updates) is greater than the version in Jammy. Hopefully, the version of samba in jammy-proposed will migrate soon.

summary: - Dist upgrade from focal to jammy fails when upgrading ubuntu-desktop,
- breaking gnome-control-center
+ Dist upgrade from focal to jammy fails to calculate due to libsmbclient
+ being greater in focal

samba has now migrated in jammy and when I tested an upgrade from Focal to Jammy it was successfully calculated, subsequently I'm setting this to Fix Released.

I can confirm that a dist-upgrade from focal to jammy now works in a fully up-to-date focal VM.
